' (o1. ca -7) 2 Claims.

This invention relates to a bracelet of the type which is comprised of two halves or parts hinged together at one point and clasped for separation at a diametrically opposite point and more particularly relates to the hinge which joins the parts together.

In a bracelet of the type here referred to frequently the two parts which are hinged together are tubular half circular arcs and it is difficult to provide a concealed hinge so that the two parts will come close together in end to end adjac'ency and yet will swing so that these two parts will clear each other in such swinging.

One of the objects of this invention is to provide a hinge which is so arranged that the bracelet ends may come close together and yet when swung to open the bracelet the ends of the two parts will clear each other.

Another object of this invention is to provide a hinge which is complete within itself and may be inserted into each of the tubular sections and there fixed in place.

Another object of this invention is to provide a hinge from sheet stock and yet one which will nicely t into tubular sections of standard size.

Another object of this invention is to provide a hinge connection by bending sheet metal stock.

Another object of this invention is to provide a connection between the hinge part-s by offsetting a tongue on one part to extend between ears or spaced projections on the other part to provide the pivotal connection in the desired location.

Another object of this invention is to provide a hinge connection which will have its pivotal axis closely adjacent the outer cleavage line between two sections of the bracelet which are connected together and adjacent the outer arcuate periphery thereof.

With these and other objects in View the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figl 1 is a sectional view illustrating fragmentally the ends of the bracelet which are to be connected by my new hinge construction and illustrating in dotted lines the position to which one of the sections may be swung relative to the other section;

Fig. 2 is a perspective view of one of the hinge members;

Fig. 3 is a perspective view of the other' of the hinge members;

Fig. 4 is a perspective View of a modified form of the hinge member; and

Fig. 5 is a perspective View of a hinge member which cooperates with the hinge member of Fig. 4.

In proceeding with this invention I provide two members which may be inserted into tubular ends of the bracelet sections which are to be connected together and I provide for movement between these two members around a pivotal axis which is so located that as one section is swung relative to the other section its rst movement will be upwardly and outwardly of the outer peripheral arc of the members so that the edges of the tubular sections will clear one another and this connection is so constituted by reason of the shape of the hinge that the sections may swing through a substantial arc before any limiting of the movement is encountered by reason of parts coming in contact one With the other.

More specifically I pivotally connect the two hinge members at a point adjacent the outer curvature of the sections connected.

With reference to the drawings I provide a bracelet section iii and a bracelet section II. The end I2 of the section i9 and end i3 of the section Il are in adjacency along a line which extends through the radius of curvature of the sections ID and I I. The sections are each tubular providing open ends for the reception of a hinge to connect these sections together.

The hinge consists of a member I4 and a cooperating member I5. The body part of each of these members I4 and i5 is arcuate in form as at I6 and I'I so as to nicely fit into the hollow ends of the sections Iii and II. These members Ifi and I5 are pivotally connected together.

The hinge connection comprises ears i9 on the upper edge I8 of section i5 each provided with an opening 29 while a tongue 2I provided on the section I4 is offset upwardly as at 22 and provided with a rolled eye 23 of a size to t between the ears I9 and align with the openings 29 so as to receive the pintle pin M which will be headed over at its ends so as to remain in position.

In the modified form section Iii which will cooperate with the section I5 as above described has a tongue 25 which is offset as at 2G to provide a portion 21. This portion 2li has outwardly extending trunnions 2:3 to be received in the openings 20 of the section I5. The offset 26 will be of a length to reach up to the ears I9 for hinge connection therewith.

Referring to Fig. 1 it will be noted that the axis 24 of the pivotal connection is located closely adjacent the end I 3 of the section H and also closely adjacent the inner surface 30 of the outer wall 3| of the section il. Thus as the section I0 is moved relatively to the section Il as shown in dotted lines t'he edge 32 of this section i0 will clear the end of the Wall 3l of secti-on Il by rst moving outwardly as the sections yare swung one relative to the other. The tongue portion Z2 by leading from the inner curvature 33 of the section i0 outwardly to the pivotal point 24' and extend` ing a substantial distance from the body oi section I d provides a pocket into which the edge wall 3l of the section Il may extend as the hinging occurs so that these sections may be moved a substantial extent one on the other around the pivotal aXis of the pin 24.

I claim:

1. In a bracelet, a pair of arcuate sections each having a substantially round tubular end portion in end to end adjacency and having inner and outer walls, a hinge connecting said sections comprising a pair of members, one member held in one section and the other member held in the other section, a tongue fixed on one member at substantially the edge of the inner wall of one arcuate section and extending across the joint between the sections and pivotally connected to the other member at substantially the edge oi the outer wall of the other arcuate section whereby the -section in which the tongue is xed is moved outwardly upon initial swinging about the hinge connection to cause its end to clear the end of the other section in which the pivot is located.

2. A bracelet as set forth in claim I wherein said pivotal means comprises ears having openings therein on one member and said tongue has outwardly extending trunnions to extend into the openings in said ears.
